To all whom it may concern:

Be it known that I, ELMER HUBBARD, a

citizen of the United States, residing atv Gilboa, in the county of-Schoharie and State of New York, have invented new and usefulImprovements in Combined Traction Stone-Crushers and Rollers, of whichthe following is a specification.

The purpose of this invention is the provision in a single machine ofmeans whereby stone may be crushed for surfacing a roadway, the crushedstone graded and then deposited uponthe roadway inlayers of as sortedsizes, means for rolling the roadway, and a machine which may be used asa traction engine for hauling loads or for performin any desired workrequiring power.

The lnyention consists of the novel features, details of constructionand combination of parts, which hereinafter will be more particularlyset forth, illustrated in them:- companying drawings, and pointed out inthe appendedclaims.

, Referring to the drawings, forming a part of the specification, Figure1 is a side view of a machine embodying the invention. Fig. 2 is a topplan 'view thereof. Fig. 3 is a vertical section on the line m"-a2 ofFig, 2. Fig. 4 is a sectional view of the stone crusher. Fig.5 isasectional detail on the line 55 of Fig. 2, showing the parts on alargerscale.

Corresponding and-like parts are referred to in the followingdescription, and indicated in all the views of the drawings, by the samereference characters.

The main frame of the machine is indicated at 1 and maybe of any desiredconstruction. The "machine is supported upon a front roller 2 and reartraction wheels 3, the latter having-broad treads and serving as rollersto compress the surface over which the machine may be propelled. A.steam boiler 4 is mounted upon the main frame upon the rear thereof andmay be of any design. An engine 5 is secured to the boiler and issupported thereby. The boiler and engine are provided with the usualadjunctive parts for safety. The traction wheels 3 besides serving asrollers constitute drivers for propelling the machine. 6 forms a part ofor is fitted to each of the traction wheels and meshes with a pinion 7upon a transverse shaft 8. A gear wheel 9 fastened to the shaft 8 is inmesh with an idler 10, which latter in turn is in mesh with Gog gearinga pinion 11 on a crank shaft 12. The crank shaft 12 is connected withthe engine 5 in the usual manner so as to be drivensthereby.

A suitable clutch 13 is employed fort-browing the drive gearing into orout of action so that the machine as a whole may remain stationary whilethe 1 stone crusher and separating mechanisms are in operation.

The roller 2 is journaled in a frame which is mounted to turn'about avertical axis, said frame being movable by means of a cable 1%, which isattached at one end to an end of the frame and has its opposite endattached to a transverse shaft 15 and adapted to wind thereon. The shaft15 extends transversely ofthe machine and is adapted to be rotated. Forconvenience a shaft 16 is connected with i the shaft 15 by meansof wormgearing, said shaft 16 being adapted to be turned by the attendant. One'of the cables 14 is adapted to wind upon the shaft 15 in an oppositedirection to the other cable 14 so that as one cable is wound upon theshaft the other is unwound therefrom, thereby admitting of the roller 2being turned to direct the ma chine in the desired direction when inmotion over the road.

The crushing mechanism comprises a stationary jaw 17 and a movable, jaw18, the two jaws being upwardly diverged. A lever 19'is arranged tooperate the movable jaw 18 and has a roller 20 at its outer end incontact with an eccentric 21 of the crank shaft 12. A fulcrum roller 22is adapted to transmit power from the lever 19 to the jaw 18 and it isproposed to provide fulcrum rollers of different diameters so' that thestone may be crushed to any degree of fineness. When a larger fulcrumroller is interposed between the lever 19 and the jaw 18 the distancebetween the lower ends of the crushing jaws is materially reduced, hencethe stone is crushed to a comparatively'fine degree. By substituting thefulcrum roller of less diameter the distance between the lower ends ofthe jaws 17 and 18 is increased, hence the size ofthe crushed stoneis'proportionately increased. It will thus be understood that byselecting a fulcrum roller of required diameter any desired degree offineness of the stone crushed may be obtained. Springs 23 serve toretract the lower end ofthe movable crushing jaw 18.

A stone separator is arranged to receive the crushed stone from thecrushing jaws and comprises a frame 24: and a screen 25,

the latter having meshes or openings varying in size. It is proposed tohave the screen composed of material having different sized openings ormeshes which gradually increase in size from rear to front. One screenmay be replaced by another of difierent 'mesh.

The frame 24: is suspended from the frame 1.

by'means of hangers 26 and is adapted to have a vibratorymovement'imparted thereto. Rods 27 connected at one end to the frame 24have eccentric connection 28 at their opposite ends with the crank shaft11.

In the rotation of thecrank shaft a vibra-- .ing 6 and adapted to beengaged by clutch sleeves 31 slidable on the shaft 30 and prevented fromturning thereon. The shaft 30 is fixed and the clutch sleeves 31 aremovable thereon by means of a lever 32.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled inthe artto whic I the invention appertains, andwhile I have described theprinciple of operation of the invention, together with the device whichit now consider to be the embodiment thereof,

I desire to have it understood'that the device shownis merelyillustrative; and that such changes may be made when desired as areWithin the scope of the claims appended hereto.

Having thus described the invention what is claimed as new, is p 1. Acombined road roller, stone crusher and separator comprising a mainframe, rotary supports therefor having a broad tread and constituting*the road rolling means, a stone crusher carried by the main frame, aseparator for the crushed stone supported by the main frame in positionto receive the stone from the crusher, an engine mounted upon the mainframe, and connecting means between the engine and the stone crusher,

noeaaeo separator and rolling supports, whereby the machine may besimultaneously propelled over the road to apply crushed stone to thesurface thereof and to roll the stone into the surface of the road.

2. A combined road roller, stone crusher and separator comprising a.main frame,

rolling supportsfor the main frame constituting the road rolling means,a stone crusher, a separator, an engine mounted upon the maln frame,connecting means between said engine and the stone crusher and:separator, and other-connecting means between the engine and therolling supports for propellingthe machine over the road, the lastmentioned connecting means includinga clutch to admit .of throwing thedrive gearing into or'out of action.

3. A combined road roller, stone crusher and separator comprlsing a mainframe, a

1 roller supporting one end .of the main frame and mounted to admitof-steering the same,

traction Wheels supporting the opposite end of the main frame, coggearing secured to the inner sides of the traction wheels, a stonecrusher and a separator mounted upon the main frame, an engine carriedupon the main frame, a crank shaft, connecting means between the engineand crank shaft, other connecting means between the crank shaft and thestone crusher and separator, other connecting means between the crankshaft and the cog gearing of the traction wheels including a clutch, afixed shaft, clutch members mounted upon the fixed shaft and adapted tohave a longitudinal movement thereon only, gear elements loose upon the,

fixed shaft and in mesh with the cog gearing of the traction wheels andprovided wlth half clutches to be engaged by the said clutch members,and means for throwing the clutch members into engagement with the halfclutches and the gear elements to hold the machine stationary when thedrive gearing is thrown out of action.

In testimony whereof I afiix my signature in presence of two witnesses.

ELMER- HUBBARD.
